The MIN/MAX function is switched OFF, when the MIN/MAX pushbutton
(3) is pressed for approximately 1s, or when the function selector switch
(6) is operated, or when the meter is turned OFF and ON again.
Notes :
The 30 mV
and 300 mV
measuring ranges can only be selected
manually with the ’’ AUTO/MAN ’’ pushbutton (4) !
On the 1000 V r ange, an intermittent sound signal warns you, when the
measured value exceeds the upper range limit.
Caution :
Ensure current measuring range (’’mA’’ or ’’A’’) is not selected for voltage
measurement ! When the cut-out rating of the fuses is exceeded because
of incorrect operation, a dangerous situation exists!.
Zero adjustment on the 30 mV
measuring range
Connect the test leads to the meter and join the free ends.
After having selected the measuring range, briey press the yellow multi-
function pushbutton (5).
The meter acknowledges zero setting by a sound signal, the LCD shows
’’00.00’’ (+ 1 digit) and the decimal point ashes. The displayed voltage
at the instant the pushbutton is pressed, is used as reference value
(max + 200 digits) it is automatically deducted from the values measured
thereafter.
The zero adjustment is cleared when ;
By pressing the yellow multifunctionpushbutton (5) for a long time,
clearance is acknowledged by the two sound signal.
By switching the instrument OFF.
8. Voltage measurement
According to the voltage to be measured , set the function selector
switch (6) to V
~,
V
or V
.
Connect the test leads as shown. The ’’
’’ socket should be
connected to the lowest potential ground available.
